yes, it is enabled. double check and I have the real server with ip forwarding just in case (in fact i will put everything i can with ip forwarding even the microware is it nedeed) [root@node1 ~]# sysctl -p net.ipv4.ip_forward = 1 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 Quoting GSR-Linux <gsrlinux@xxxxxxxxx>:
Just check if port forwarding is enabled. in your lvs router.
